Why can I not set all the DDR data rate ratios that the reference manual says are supported by the RCW “MEM_PLL_RAT” field bits 10-15?

There is a footnote in the T4240 reference manual that states “Not all ratios are supported due to frequency restrictions. Refer to the hardware specifications for the supported frequencies."


Hope it helps

Do you try to use QCVS? Or what is your scenario?
